Effectiveness of HIV prevention interventions in developing countries.

Abstract

This review demonstrates that HIV prevention interventions can be effective in changing risk behaviors and preventing transmission in low and middle-income countries. When the appropriate mix of interventions is applied, they can lead to significant reductions in the prevalence of HIV at the national level. Additional research is needed to identify effective interventions, particularly in men who have sex with men, youth, IDUs and HIV-infected persons. Structural and environmental interventions show great promise, although more evaluation is needed.
